我将此代码用于带有分页的自定义循环:

    $paged = get_query_var('paged');
} elseif ( get_query_var('page') ) { // 'page' is used instead of 'paged' on Static Front Page
    $paged = get_query_var('page');
} else {
    $paged = 1;
}

$custom_query_args = array(
    'post_type' => 'post', 
    'posts_per_page' => get_option('posts_per_page'),
    'paged' => $paged,
    'post_status' => 'publish',
    'ignore_sticky_posts' => true,
    //'category_name' => 'custom-cat',
    'order' => 'DESC', // 'ASC'
    'orderby' => 'date' // modified | title | name | ID | rand
);
$custom_query = new WP_Query( $custom_query_args );

if ( $custom_query->have_posts() ) :
    while( $custom_query->have_posts() ) : $custom_query->the_post(); ?>

        <article <?php post_class(); ?>>
            <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
            <small><?php the_time('F jS, Y') ?> by <?php the_author_posts_link() ?></small>
            <div><?php the_excerpt(); ?></div>
        </article>

    <?php
    endwhile;
    ?>

    <?php if ($custom_query->max_num_pages > 1) : // custom pagination  ?>
        <?php
        $orig_query = $wp_query; // fix for pagination to work
        $wp_query = $custom_query;
        ?>
        <nav class="prev-next-posts">
            <div class="prev-posts-link">
                <?php echo get_next_posts_link( 'Older Entries', $custom_query->max_num_pages ); ?>
            </div>
            <div class="next-posts-link">
                <?php echo get_previous_posts_link( 'Newer Entries' ); ?>

• WordPress custom loop with pagination

很棒,一如既往.作为对此的附录,请考虑以下情况:正在使用附加到Page的全局页面模板获取一些"介绍性文本",然后是要分页的子查询.

使用上面提到的paginate_links(),主要使用默认值,(并假设漂亮的永久链接已打开),您的分页链接将默认为mysite.ca/page-slug/page/#,这很可爱,但会由于WordPress不知道而引发404错误有关该特定网址结构的信息,实际上将查找"page"的子页面,而该子页面是"page-slug"的子页面.

这里的窍门是插入一个巧妙的重写规则,该规则仅适用于接受/page/#/结构并将其重写为一个查询字符串的特定"伪存档页面"页面段WordPress可以理解,即mysite.ca/?pagename=page-slug&paged=#.注意pagename和paged而不是name和page(这确实使我感到悲伤的时光,在这里激发了这个答案！ ).

这是重定向规则:

 add_rewrite_rule( "page-slug/page/([0-9]{1,})/?$", 'index.php?pagename=page-slug&paged=$matches[1]', "top" );
 

与往常一样,在更改重写规则时,请记住通过访问管理后端中的"设置">"永久链接"来清除永久链接.

如果有多个页面将以这种方式运行(例如,当处理多种自定义帖子类型时),则可能要避免为每个页面段创建新的重写规则.我们可以编写一个更通用的正则表达式,该正则表达式适用于您确定的任何页面信息.

下面是一种方法:

 function wpse_120407_pseudo_archive_rewrite(){
    // Add the slugs of the pages that are using a Global Template to simulate being an "archive" page
    $pseudo_archive_pages = array(
        "all-movies",
        "all-actors"
    );

    $slug_clause = implode( "|", $pseudo_archive_pages );
    add_rewrite_rule( "($slug_clause)/page/([0-9]{1,})/?$", 'index.php?pagename=$matches[1]&paged=$matches[2]', "top" );
}
add_action( 'init', 'wpse_120407_pseudo_archive_rewrite' );
 

缺点/警告

这种方法的一个缺点是使Page slug硬编码,这使我有些不耐烦.如果管理员曾经更改过该伪归档页面的页面标签,那么您将敬酒-重写规则将不再匹配,您将获得可怕的404.

我不确定是否可以考虑此方法的解决方法,但是如果是全局页面模板以某种方式触发了重写规则,那就太好了.有一天,如果没有其他人能破解那个特殊的螺母,我可能会重新审视这个答案.

Awesome as always Chip. As an addendum to this, consider the situation whereby you are using a global page template attached to a Page for some "intro text" and it's followed by a subquery that you want to be paged.

Using paginate_links() as you mention above, with mostly defaults, (and assuming you have pretty permalinks turned on) your pagination links will default to mysite.ca/page-slug/page/# which is lovely but will throw 404 errors because WordPress doesn't know about that particular URL structure and will actually look for a child page of "page" that's a child of "page-slug".

The trick here is to insert a nifty rewrite rule that only applies to that particular "pseudo archive page" page slug that accepts the /page/#/ structure and rewrites it to a query string that WordPress CAN understand, namely mysite.ca/?pagename=page-slug&paged=#. Note pagename and paged not name and page (which caused me literally HOURS of grief, motivating this answer here!).

Here's the redirect rule:

add_rewrite_rule( "page-slug/page/([0-9]{1,})/?$", 'index.php?pagename=page-slug&paged=$matches[1]', "top" );

As always, when changing rewrite rules, remember to flush your permalinks by visiting Settings > Permalinks in the Admin back-end.

If you have multiple pages that are going to behave this way (for example, when dealing with multiple custom post types), you might want to avoid creating a new rewrite rule for each page slug. We can write a more generic regular expression that works for any page slug you identify.

One approach is below:

function wpse_120407_pseudo_archive_rewrite(){
    // Add the slugs of the pages that are using a Global Template to simulate being an "archive" page
    $pseudo_archive_pages = array(
        "all-movies",
        "all-actors"
    );

    $slug_clause = implode( "|", $pseudo_archive_pages );
    add_rewrite_rule( "($slug_clause)/page/([0-9]{1,})/?$", 'index.php?pagename=$matches[1]&paged=$matches[2]', "top" );
}
add_action( 'init', 'wpse_120407_pseudo_archive_rewrite' );

Disadvantages / Caveats

One disadvantage of this approach that makes me puke in my mouth a little is the hard-coding of the Page slug. If an admin ever changes the page slug of that pseudo-archive page, you're toast - the rewrite rule will no longer match and you'll get the dreaded 404.

I'm not sure I can think of a workaround for this method, but it would be nice if it were the global page template that somehow triggered the rewrite rule. Some day I may revisit this answer if no one else has cracked that particular nut.

我已经通过query_posts()修改了主循环查询.为什么分页不起作用,如何解决?

很好的答案创建的芯片现在需要修改.
一段时间以来,在执行主查询后,我们就有了$wp_the_query变量,该变量应该等于$wp_query全局变量.

这就是为什么此部分来自芯片的答案:

没有主查询对象

不再需要. 我们可以通过创建临时变量来忘记这一部分.

 // Pagination fix
$temp_query = $wp_query;
$wp_query   = NULL;
$wp_query   = $custom_query;
 

现在我们可以打电话给

 $wp_query   = $wp_the_query;
 

甚至更好,我们可以致电:

 wp_reset_query();
 

其他所有Chip概述的住宿项目. 在查询重置部分之后,您可以调用f($wp_query)的分页函数,它们依赖于全局$wp_query.

为了进一步改善分页机制并赋予query_posts函数更多的自由,我创建了以下可能的改进:

https://core.trac.wordpress.org/ticket/39483

I have modified the main loop query via query_posts(). Why isn't pagination working, and how do I fix it?

Great answer Chip created needs to be modified today.
For some time we have $wp_the_query variable that should be equal to the $wp_query global just after the main query executes.

This is why this the part from the Chip's answer:

Hack the main query object

is not needed anymore. We can forget this part with creating the temporary variable.

// Pagination fix
$temp_query = $wp_query;
$wp_query   = NULL;
$wp_query   = $custom_query;

So now we can call:

$wp_query   = $wp_the_query;

or even better we can call:

wp_reset_query();

Everything other Chip outlined stays. After that query-reset-part you can call the pagination functions that are f($wp_query), — they depend on $wp_query global.

In order to further improve the pagination mechanics and to give more freedom to the query_posts function I created this possible improvement:

https://core.trac.wordpress.org/ticket/39483

 global $wp_query;
        $paged = get_query_var('paged', 1);

        'meta_query' => array('{add your meta query argument if need}'),  
        'orderby' => 'modified',
        'order' => 'DESC',
        'posts_per_page' => 20,
        'paged' => $paged 
    );
    $query = new WP_Query($args);

    if($query->have_posts()):
        while ($query->have_posts()) : $query->the_post();
            //add your code here
        endwhile;
        wp_reset_query();

        //manage pagination based on custom Query.
        $GLOBALS['wp_query']->max_num_pages = $query->max_num_pages;
        the_posts_pagination(array(
            'mid_size' => 1,
            'prev_text' => __('Previous page', 'patelextensions'),

            'before_page_number' => '<span class="meta-nav screen-reader-text">' . __('Page', 'patelextensions') . ' </span>',
        ));
    else:

        'order' => 'DESC',
        'posts_per_page' => 20,
        'paged' => $paged 
    );
    $query = new WP_Query($args);

    if($query->have_posts()):
        while ($query->have_posts()) : $query->the_post();
            //add your code here
        endwhile;
        wp_reset_query();

        //manage pagination based on custom Query.
        $GLOBALS['wp_query']->max_num_pages = $query->max_num_pages;
        the_posts_pagination(array(
            'mid_size' => 1,
            'prev_text' => __('Previous page', 'patelextensions'),
            'next_text' => __('Next page', 'patelextensions'),
            'before_page_number' => '<span class="meta-nav screen-reader-text">' . __('Page', 'patelextensions') . ' </span>',
        ));
    else:
    ?>
        <div class="container text-center"><?php echo _d('Result not found','30'); ?></div>
    <?php
        endif;
